1.375in O.D. 90 Degree Mandrel Bend

The Vibrant Performance 1.375in O.D. 90 Degree Mandrel Bend (Part #13031) is a precision exhaust component engineered for custom exhaust system fabrication and modification. This stainless steel mandrel bend features a 1.375-inch outer diameter with a 2.375-inch radius and 4 x 12-inch legs, delivering the smooth, consistent internal geometry required for optimized exhaust flow and minimal turbulence in high-performance applications.

Constructed from 16-gauge stainless steel, this mandrel bend resists corrosion and thermal degradation in demanding exhaust environments. The mandrel manufacturing process ensures the inside radius remains consistent without collapse or deformation, critical for maintaining backpressure efficiency and scavenging characteristics. The 2.375-inch radius follows industry-standard tubing proportions, making this component compatible with common exhaust fabrication specifications and turbo manifold applications where controlled bends are essential.

This bend is designed for builders, fabricators, and technicians constructing custom exhaust systems for street cars, race vehicles, and performance-modified engines. Whether routing exhaust around engine bay obstacles or optimizing flow paths for turbocharged platforms, a quality mandrel bend eliminates the tube collapse and kinking that reduces flow and increases emissions. Vibrant Performance's 90-degree bend integrates seamlessly into modular exhaust builds where precision fitment and repeatability matter.

Mandrel bends are foundational components in any fabricator's toolkit. Unlike welded bends or crude pipe bends, mandrel-formed tubing maintains wall thickness and internal diameter consistency, preventing flow restrictions and extending component life. This 1.375-inch size serves a wide range of applications, from small-displacement turbocharged engines to mid-sized naturally aspirated builds requiring clean routing and maximum efficiency.
